well i hooked up my hks evc to my agp s3 delta witch has an external wastegate and something is not right. i hooked it up just like the book says to for external wastegate and all i get is 9 psi, which is my spring rate. i set the target boost for 16 psi. i even reversed the lines at the wastegate and ya i got more boost but way to much and its uncontrolable. just was wanting to know who all is running this and if they could lead me in the right direction. i've adjusted the correction coefficient and nothing, just a few tenths. its still in early setup so i'm going to keep going threw all the different features trying to figure it out, just thought if someone here has it and has figured it out, maybe its something i overlooked or something that is not in the book. also just curious as to what vacuum reading someones getting at idle, just to compare.

I do not run an External Wastegate but I do have an HKS EVC EZ (the original). On the back of the boost controller is a switch. Once to go to an External Wastegate, you must flip the switch. This should solve your problem. Good Luck.
